Seperate messages in ingame message system

Change it so that different type of messages in in-game message system (icon left of friends icon) are displayed in different categories, i propose next categories:

1. Private messages from people
2. Messages of planned assault and assault aborting
3. Messages of planned gang assault and assault aborting
4. Messages of Fight club challenges
5. Messages of gang leaders and co - leaders
6. Messages of friend requests and friend deletion

All those categories could be picked from a drop down menu, so you don't have to delete thousands of messages to see if any of your friends or potential gang recruits wrote to you while you were robbing or hunting with a gang.

Currently all messages are put into category called System messages as displayed in a picture below, this makes it hard to navigate through all messages (especially every confirmation of successful gang robbery) and find one you are interested in.
